During the last GPU mining craze, I helped build a 3-rack mining operation. Gpus are unregulated pieces of power-sucking shit from a power management perspective. You do not have the power requirements to do this on residential power, even at 300amp service.
Think of a microwave's behaviour ; yes, a 1000w microwave pulls between 700 and 900w while cooking, but the startup load is massive, almost 1800w sometimes, depending on how cheap the thing is.
GPUs also behave like this, but not at startup. They spin up load predictively, which means the hardware demands more power to get the job done, it doesn't scale down the job to save power. Multiply by 58 rx9070. Now add cooling.
You cannot do this.
If you have 3 phase you could reasonably do this. This is not very common but some people have it in which case running about 50 rx9070 plus a strong AC should be possible, I think.
I guess. I don't know why a person would do this, though... Especially just for an LLM.

Thanks, While I still would like to know thr peformance scaling of a cheap cluster this does awnser the question, pay way more for high end cards like the H200 for greater efficiency, or pay less and have to deal with these issues.
